Things to Note During A Toilet Bowl Installation in Singapore
Installing the toilet bowl properly is crucial for your safety, avoiding the leaks and the bad odours. If you make any mistakes in it or be careless, it can cost you a lot of money to repair and also the inconveniences that stay for months until it’s fixed. So, these are the things to note during a toilet bowl installation in Singapore so you can do it properly.
Check The Toilet Bowl Size And Type
Before you buy a toilet bowl, you need to know if it will fit. Not every toilet bowl is the same size. Some are longer, some are rounder.Â
You also need to check if it matches your bathroom pipes. In Singapore, most toilets use a standard size, but it’s always better to check first. If you buy the wrong type, you might waste time and money. It could also mess up your bathroom setup later.
Turn Off The Water Supply
The first thing you should do before starting any work is to stop the water. You can do this by turning off the valve near the toilet. This stops water from flowing when you remove the old toilet. If you forget this step, be ready for a big mess.Â
Water could spill everywhere, and trust me, nobody wants that. A small twist of the valve saves a lot of headaches later.

Remove The Old Toilet Bowl Carefully
You cannot rush this step. You need to unbolt the toilet from the floor slowly. Most toilets are held with a few screws or bolts. Once you take them out, lift the bowl gently. It might feel heavy, so get a hand if you need one.Â
Keep it aside and then clean up all the mess which is leftover. Carefully check if the water is still inside the bowl trapped around the seal. If it is, remove it out from there.
Check And Clean The Floor Flange
After you take out the old toilet, have a good look at the flange. This is the ring on the floor where your toilet sits.
If it’s cracked or looks worn out, you’ll need a new one. No way around it. Scrape off the old wax stuck on it with a putty knife or something flat. If this part’s bad, your toilet’s going to rock or leak later. Better to fix it now than curse it later.
Place The New Wax Ring Carefully
This part’s pretty simple, but people mess it up all the time. The wax ring seals the toilet so water and smells don’t escape. You just press it onto the bottom of the toilet, flat and even. Don’t shove it too hard or leave it hanging half-off.Â
If it’s not sitting right, you’ll know later when the floor’s wet or the bathroom smells funny. Do it once, do it right.
Position The Toilet Bowl On The Flange
Now’s the part where you line up the toilet with the bolts on the floor. Go slow. You only get one good shot at setting it down straight.Â
If you drop it wrong, the wax won’t seal, and you’ll have to start over. Once it’s lined up, push it down with even pressure. You want the toilet sitting flat, not tilted like a seesaw. Take your time.
Tighten The Toilet Bowl To The Floor
Grab the nuts and tighten the bolts by hand first. Don’t crank them down like you’re fixing a car tire. Go little by little on each side.Â
If you tighten one too much, the bowl can crack, and then you’re shopping for a new one. The toilet should feel steady when you give it a small wiggle. If it rocks, tighten a bit more, slowly.
Turn The Water Supply Back On
Once the toilet’s down, open the water valve. Let the tank fill while you watch. Look under the tank and around the base for leaks.Â
If you see a drip, stop and check your connections. It’s better to catch a leak now than to find it after you’ve walked away. Don’t rush this. A five-minute check saves you a headache later.
Check The Toilet For Leaks And Make Sure It Flushes
Time for the real test. Hit the flush and watch what happens. Does it drain right? Any water leaking at the base?
 Check where the hose connects too. Sit on the toilet and make sure it feels steady. If something’s off, fix it now. If it looks good, you’re done. Simple as that.

Seal The Base With Waterproof Silicone
After you’re sure the toilet works fine, it’s time to seal the base. You should use waterproof silicone around the bottom of the toilet.Â
This helps stop water from seeping under the toilet if the floor gets wet. It also keeps dirt and bad smells from hiding in the cracks. You don’t need a thick line of silicone. A small, neat bead will do the job just right.
Final Words
These are the things to note during a toilet bowl installation in Singapore. Make sure the toilet fits your space, then shut off the water to avoid a mess. Remove the old toilet gently, clean the floor flange, and fix or replace it if it’s damaged.
Press the wax ring onto the toilet base, then lower the toilet straight onto the flange without shaking it. Lastly, tighten the bolts just enough to hold it firm, turn the water back on, check for leaks and give it a test flush.
